You might check for an air leak, usually when it runs better with the choke on, you have a lean condition. If the machine sat for a while, you may just need to clean the carb better, manually push things throught the jets and blow them out with compressed air. Also, remove the pilot screw and make sure the pilot circuit is clean. The only sensor on the carb is the throttle position sensor, and that used to match the timing curve to the throttle position.

Did they tell you what an ASC sensor is? I am curious to know what that is. Does it have anything to do with the reverse throttle override that limits the engine speed while it is in reverse? Does this mean that you have not throttle limiter when you are in reverse? Because that would be kind of cool, I have always been annoyed by the reverse throttle limiters that they put on quads that have reverse. The only ASC sensor I have ever heard of is in automobiles and it is part of the Active Stabilitly Conrol system which usually works on conjuntion with the brake system.

I didn't know they had a sensor in the intake system! I gotta call BS on that one- I'm headed for the parts catalog.

Otherwise it had to be an air, vacuum leak somewhere. Several guys were right.

Hey Demon: the 01 Raptor 660r does NOT have a reverse limiter... all the rest do. If you really want to flip you gotta try it in reverse! LOL

I'm in agreement with you, the only sensor that I know of it the TPS, and that only detects the throttle position for the purpose of optimizing the timing curve.

A bike without a reverse limiter sounds like fun to me:biggrin:.
